The transverse displacement of a string is given by `y ( x , t ) = 0.06 sin ((2pi)/(3)) x cos ( 120 pi t)` where 'x' & 'y' are 'm' and 't' is s. The length of the string is 1.5m and its mass is `3.0 xx 10^(-2) kg`.
Does the function represent a travelling wave or stationary wave ?

Explanation

The given equation is,
`y( x,t) =0.06 sin ((2pi)/(3))x cos(120pit)`comparing this with
`y =2Asinkx cos omega t ` we conclude that the equation represents the stationary wave.
